Step Seventeen
Continue painting out a part of the letters, copying, pasting after current and placing the pen till you get to the last few pixels of the first letter.
Here are a few screenshots along the way to help you.

Notice with the M that shadow was painted in where the end tag was rather than background color.

Sometimes you can use the same frame copied twice with the pen place at different parts of the letter.
If you run out of pen frames just duplicate the last frame again to create some more.
Remember always that you are writing the letters backwards and they sometimes may look strange when you are doing them.

One of the most important letters to remember is lower case 'i'. Always take out the dot first before the stalk of the 'i'

Long strokes are better done all as one pen stroke, the finished effect looks better.
Remember also that the shadow may get lighter and darker depending on its placement. You may have to adjust your background color accordingly using the dropper tool.
Take your time with this as it is more difficult to go back and change something than with PSP. Going back to redo may involve deleting several frames.
With a letter like O or Q, the easiest way is to split it in half:

Step Eighteen
When you reach the last part of the first letter, leave a couple of pixels as a marker to yourself then place the pen on frame 1.

Step Nineteen
Save the image. Pen signatures can give quite a large file size so you may have to choose to have less colors to make the file size smaller. Use your judgement when compromising image quality for file size. I typically use level 3 quality on the first part of the save wizard.

Your finished signature should look something like this:

There are many variations you can give a pen signature, you are only limited by your imagination. Here are a few examples:
    
The ones with no pen that seem to write themselves are slightly more difficult but with practise can be done.
